Forum d’assistance Firefox

I've recently been having troubles playing videos on Firefox.

My school website uses Vimeo embeds, but recently when I've put the videos in fullscreen, after 4-5 seconds it stops responding. The video freezes but the audio continues, and the controls don't come up when I move the mouse. I can press ESC to exit fullscreen, but the controls are still gone and the audio keeps playing. Then after a few more seconds I get the warning "This page is slowing down Firefox, to speed up your browser stop this page".

If I don't use fullscreen but instead zoom in on the page, it also freezes. If I try the same things with Edge it does not freeze. I also made sure that it was only affecting Vimeo videos, by testing with other platforms and other vimeo links.

I found previous reports of this issue, but all of them were either on Linux, or it was an issue with flash player, which is not relevant anymore.

Not quite sure how to debug this but I would be happy to provide further info. It's really important that it works again :/ Thanks in advance!

My repro steps: 1. Find a video on https://vimeo.com/watch 2. Play it and enter fullscreen 3. Wait around 6 seconds

AndyMark.com is displaying as a mobile site and unusable. No option in Firefox to request desktop site. Running Windows 10. Instructions online say to go to Firefox menu and select desktop site but that option is no longer available. I realize that Windows is a phone operating system but my phone is Android and my laptops are Windows and I use Windows no my computer. Firefox is unusable if we can not set it to always use desktop views.

Please put the option back. Thank you.

For the last several weeks, the reliability of Firefox has went off a cliff following an auto-update. After a few hours of browsing, it gets to the point where the tabs load extremely slow (or not at all). When this happens, I exit and relaunch.

Previously, it would be nearly instantaneously where the windows would close and the firefox.exe process would cease within seconds. Now, it's taking upwards of 5-10 minutes for the process to stop AFTER the windows have closed and, during that time, it'll bring the system to a near crawl. Once the process finally closes though, everything is back to working fine.

I suspect that my bank tried to show a verification pop-up while I was on a third-party site, and because pop-ups were disabled the third party rejected my request. My question is:

How much of my bank's website address do I need to put in the "Allowed Web Sites - Pop-ups" edit box, seeing as I wasn't on that website at the time. Would "https://name-of-bank.com" be sufficient? Or, are wildcards allowed in the URL?

Twitter Video Streaming in Firefox on an older computer (Windows 7) does not work. The videos don't play (just audio). I logged into my same Twitter account on Chrome on the same computer and Twitter video streaming worked perfectly. Please fix the disparity.

As the title says, after update 107.01, passwords work in autofill, but I cannot see them when I go to "passwords" in the menu... The passwords page is just blank... Any help would be appreciated!

Whenever I open Firefox, there are some sites that are opened itself. This is very annoying. Everytime I have to close all that tabs.

Kindly tell me how can I avoid this annoying thing. Else I have to switch to another browser.

Thanks

Firefox is crashing with the following crash report bp-23ef881c-cb8d-4d69-a069-abcb70221210 would like to know the reason.

AMD Ryzen 5 2600 Six-Core Processor 3.40 GHz 16GB RAM NVIDIA GTX 1060 6GB Firefox 107.01 64Bit

I was watching Youtube and twitch on another monitor but I still had 50% ram remaining. Any feedback would be great.

Thanks

No Video with Supported format and MIME type found is not allowing me to play videos on website.

No idea what's the cause of it, I've tried everything from internet tips how to solve this.

Trying to bookmark a pdf, it's on the same location across my devices, but my devices have different usernames, so I added "%userprofile%" to the filepath so that it opens on any device. The issue is that when I enter this into the Bookmark URL bar, it automatically sticks "25" next to the % characters, which makes the bookmark unusable.

"C:\Users\%userprofile%\Documents\example.pdf" automatically becomes "file:///C:/Users/%25userprofile%25/Documents/example.pdf"

Also, as I just discovered now when I pasted this URL into this post, a second "25" is inserted, becoming: "file:///C:/Users/%2525userprofile%2525/Documents/example.pdf"

During an initial visit to slashdot.org Firefox hangs for approx 45 seconds while the status bar says "looked up a.fsdn.com." Subsequent visits during the same browser session load promptly.

This is with Preferences -> General -> Network Settings -> Enable DNS over HTTPS -> Cloudfare or NextDNS. With Firefox DoH disabled the problem is not present. [Interesting side, the machine's systemwide DNS settings are configured for Cloudfare 1.1.1.1 ]

AFAIK all other sites load normally. I've been using the Firefox DOH for several months with only the above site as a problem.

Ideas?

Environment: Firefox desktop 106.x and 107.x macOS 10.13.6 The problem is present in "Troubleshoot Mode" when Firefox DOH is enabled.

When I press the "menu" button in the top right of the screen, nothing happens. If I hover over the button, it says "open application menu" but clicking does absolutely nothing. The same happens with the account button to the left.

What can I do to fix this?

With the latest upgrade to Firefox 107.0 there is no option any more to import or manage certificates. Going to Settings/Privacy & Security/Certificates and selecting View Certificates results in a window showing installed certificates with only OK button at the bottom of the window. No option to import, delete, save or anything else. OS: OpenSuse Linux 64bit

Up until the last few months, I've been able to do a Yahoo image search, click on one of the images, and click through all the images one by one, JUST seeing the images, and NOT going to the website containing the image. Now, when I do the same search, and click on an image, it goes straight to the related website. I know it's Firefox related, because it works as it used to if I use another browser. I've cleared the cache and cookies, and Yahoo history and it still doesn't work. It was fine until a few weeks ago.

having issues with an anime website watch cartoons online, most of the episodes, on several anime(dubbed) state "timeout err" and then say unable to play vid, refresh, but no matter how many times i refresh none of the videos that i know should work are working now. i have no add ons at all, as far as im aware, no pop up blockers, no viruses detected on computer, and now at wits last end trying to figure out what the problem is...

Although I have my Browser Privacy / Enhanced Tracking Protctions setting at "STRICT": "Stronger protection but may cause some sites or content to break" and with a "Heads up!" warning that states: "This setting may cause some websites to not display content or work correctly" -- I chose to enact it, anyway, knowing taking this informed risk.

However, on a site that I just visited, I received a message (from clicking on the little duck icon) that stated: "To prevent site breakage, we didn't lock ANY companies from loading tracking requests on this page". Also, "The following third-party domains' request were loaded. If a company's requests are loaded, it can allow them to profile you, though our other web tracking potections still apply."; then listed all of the companies that were allowed to profile/track me, one that included Google. There were 8 different companies, some with more than one address!

What is the point of giving us that option if you aren't going to acknowledge or respect it?

Sorry if this question has been asked before. I am quite a new Firefox user. I have set firefox to sync, but my saved logins and passwords on for example my PC does not sync to my android tablet or phone. How do I fix this?

Hi!

I have encountered this really annoying problem on my Firefox app. I give details below. I installed Mozilla Firefox on my freshly installed Ubuntu 22.04.1 LTS. I tried installing it from Snap Store. However, when I tried saving an image from the web (or, truthfully, any other file chosen by the "Save As..." selection), nothing happened, again and again. I tried many things, including following relevant guides from the internet, but nothing changed. The Firefox version is the 107.0.1 (64-bit), a Mozilla Firefox Snap for Ubuntu canonical-002- 1.0. I, also, have to report some other things, as well. When tried installing the browser from the internet (I downloaded a compressed file, containing the executable), the same function seemed to work. I, now, use the executable to access Firefox. However, firstly, because other difficulties (not problems, but difficulties) arise and, secondly, because I'd really like ti use, mostly, snaps, I report this bug here requesting for help, as well.

Any helpful answer will be appreciated!

Thank you!

I have recently updated my site to run off a different hosting provider, and CloudFlare, a long needed change to my site. However, in doing so, my site has become unreachable on my laptop, with firefox (and other browsers) still thinking that my domain is attached to the old nameservers, causing it to redirect to the "site not found" page of my previous hosting provider. I have tried flushing my system's DNS cache, clearing my browser cache, clearing the browser's DNS records, all to no avail, however, I do know my site works, as on my mobile phone with basic Safari, the site works fine.

my system is on Ubuntu 22.04, and running firefox version 107.0
